    I've never seen a Laptop put out voltage on the USB ports when Off / Hibernated. Desktops, sure.

    my laptop does NOT put out power when in hibernate, or standby for that matter

    usb is completely shut off, which is the way i like it :T

    hmm, my desktop shuts all power to the usb as well, but for some mobo's that might be an option i suppose, to keep the usb's running, i wouldnt know, dont have any mobos with any options like that, lol
